out what happened when the gunman opened fire at los angeles international airport. this as the slain tsa officer's wife speaks out. >> he was a very good person. he took pride in his duty for the american public. >>> show of force. extra-tight security as some 45,000 athletes prepare to run in today's new york city marathon since the first time since both superstorm sandy and the boston bombing. >>> and what the hail? a fantastic finish at the end of the nebraska/northwestern football game.
